Patented May 6, 1930 UNITED STATES PATENT OFFICE' EDWARD ERICKSON,DECEASED, LATE 0F BEVERLY, MASSACHUSETTS, BY MARY E. ERICKSON,EXECUTRIX, 0F BEVERLY, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOE MACHINERYCORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEYFLUID-APPLYING MACHINE Application led February 26, 1927. Serial No.171,317.

This invention relates to fluid-applying .machines for use in themanufacture of boots and shoes and is illustrated as embodied in amachine arranged to apply cement to economy insoles.

Vhen machines used for applying uid to various boot and shoe parts areused in connection with soles and insoles, the diiiiculty of handlingthe. work without interference between the soles and parts of themachine becomes somewhat acute, especially when following around thedeeply indented shank portion of some such insoles. Machines have beenshown in my prior application, Serial No. 57 9,443, filed August 3,1922, upon which Letters Patent of the United States No. 1,669,508 weregranted May 15, 1928, and in application Serial No. 122,150, filed July13, 1926, in which a frusto-conical applying roll is mounted upon anaxis at the frontof the machine inclined ydownwardly-toward the rear,and in which fluid is supplied to this roll from a receptacle disposedto the rear thereof, said fluid being elevated from the receptacle andsupplied to the applying roll at a p oint remote from the point ofapplication of the work thereto.

One object of the present invention is to provide an improved machine ofthis general type having more room for the manipulation of pieces ofWork without interference with the machine.

With this in view, a feature of the invention resides in theinterposition of a novel transfer means between the uid applying memberandv the supplying member which dips in the receptacle, this transfermeans being substantially horizontally disposed above the area providedfor the manipulation of pieces of work. By reason of this constructionit is possible to provide a relatively wide separat-ion between theapplying member and the fluid receptacle to allow free manipulation ofthe Work, while maintaining a compact and efficient design. In theillustrated construction both the applying roll and the supplying rollare frusto-conical members mounted on inclined aXes and arranged tocooperate with opposite sides of the interposed disk-shaped transferroll arranged upon a vertical axis and disposed above the area providedfor the manipulation of work. The fluid receptacle is provided with alip extending beneath the transfer means arranged to underlie the pointsof co-operation between the transfer means and the supplying andapplying means, thereby to keep the cement from dripping on the work orthe floor.

Other features of the invention reside in novel mechanism` forcontrolling the quantity of fluid delivered to the applying roll byadjustably determining the relative approach of the respective rolls.construction the rolls are power-driven, and means are provided foradjusting the position of the applying roll with respect to the transferroll without impairing the driving connection to said applying roll. Asillustrated also, the applying roll and the transfer roll are mountedupon a slide normally biased to an adjustably predetermined limit inwhich the transfer roll is separated from the supplying device andoperator-controlled means are provided for moving said slide to bringthe transfer roll and the supplying device into co-operative relation.

Stilly another feature of the invention relates to a novel arrangementfor supporting the fluid receptacle in the frame of the machine to allowits ready removal for cleaning.

One specific embodiment of the invention will now be described withreference to the accompanying drawings, in which Fig. 1 is a sideelevation of the machine with parts broken awa-y and in section;

Fig. 2 is a longitudinal section taken through the axis of thefluid-carrying rolls and drawn on a somewhat larger scale;

Fig. 3 is a plan view of the machine with the cover removed and parts ofthe casing in section;

Fig. 4 is a front elevation; and

Fig. 5 is a section on the line V-V in Fig. 4 through the neck of thesupply tank.

The frame 10 of the illustrated machine is provided with a socket member12 arranged to permit the support of the machine upon the tapered upperend of a suitable pedestal 14, and an electric motor 16 is suitablysupported upon the frame of the machine so that In the illustrated themain shaft 18 of said machine may be driven from said motor through asuitable Worm and gear speed-reduction mechanism 20.

The particular embodiment of the invention herein illustrated isespecially designed for use in applying cement to economy insoles 22(Fig. 2) before the lips 24 of the insole are turned and broughttogether. For this Work a solid applying roll 26 may be used, which isof frusto-conical form and is supported for rotation upon a shaft 28 theaxis of which is inclined downwardly to the rear. The cement is suppliedto the applying roll 26 from a receptacle 30 by a cylindrical transferroll 32 supported for rotation with a vertical shaft 34 and afrusto-conical supplying roll 36 upon a shaft 38`the axis of which isinclined downwardly toward the front of the machine. The arrangement issuch that the axes of these shafts are in a common plane and intersectone another. This permits the receptacle 30 to be placed at considerabledistance from the applying roll 26 so as to give greater freedom for themanipulation of Work in contact with sald roll, it being understood thatcement is elevated from the receptacle by means of the supplying roll36, and delivered from this roll to the face of the cylindrical transferroll 32, which in turn delivers the cement to an upper point upon theapplying roll 26. In order that any dripping of the fluid at the pointsof cooperation between said rolls may be kept from soiling the Work orthe floor, the receptacle 30 is provided with a forwardly extending lip40 underlying these points but so far elevated above the plane in whichthe piece of work, such as the insole 22, is being manipulated that itdoes not interfere with said Work. )Vlien the machine is used forapplying cement, to economy insoles, a corrugated Work-supporting roll42 may be provided rotatably mounted upon the for- Ward end of an arm 44pivotally secured at 46 to the receptacle 30. A spring 48 is arranged tohold the roll 42 in yielding contact with the lower face of the Work,and an adjustable stop 50 is provided for limiting the upward movementof said roll so that it may not contact with the cement-applying roll26. A U-shaped bracket 52 formed upon the under side of the lip 40 ofthe rece ptacle serves as a guide for the forward end of the arm andco-operates with the spring 48 and the stop 50. An edge gage 54 isadjustably mounted upon the forward end of the arm 44 and is positionedin a groove 55 by means of a clamp screw.

Under certain conditions and when handling certain kinds offluid. it hasbeen found that the quantity of fluid delivered from the receptacle tothe applying roll 26 may best be controlled by adjustably determiningthe relative approach of the various rolls. Then,

too, it is important to be able to interrupt the supply of fluid to theapplying roll when Work is not being presented to the machine.Accordingly, the illustrated machine is provided With a slidable frame60 carrying the applying roll 26, the transfer roll 32 and drivingmechanism therefor. In order to support the slidable frame 60 upon theframe 10 of the machine, the slidable frame is provided with rods 62 and64 (Fig. 3) bolted to said frame at 66 and 68 and with a cross-bar 70bolted to said slidable frame and slidably mounted upon a rod 72 securedin a bracket 74 by means of a set screw 76 (Fig. 1). The bracket 74 issecured to the frame '10. A spring 78 (Fig. 3) is interposed between thebracket 74 and thevcross-bar 70 on the slide of the frame, urging thesliding frame against a wedge-shaped limiting stop 80 interposed betweena nut 82 u oifthe end ofthe rod 72 and the cross-bar 7,0. The positionof this wedge-shaped stop may be adjustably determined by means of aspring 84 urging it in one direction and the opposing action of a handwheel 86 threaded upon a bolt 88 attached to said stop and passingthrough a supporting arm 90 formed integrally with the cross-bar whichis secured to said slidable frame. The rods 62 and 64 secured to therear of the frame. 60 pass through bearings formed in lugs 92, 94 (Figs.1 and 3) upon the frame 10 and are provided with spring 96 and 98, saidsprings bearing at one side against the lugs 92 and at the other sideagainst stops 100 adjustably fixed upon the rods. Thus these springsassist the spring 78 in moving the sliding frame to its limitingposition where the transfer roll 32 is carried out of co-operativerelation to the fluid-supplying roll 36 so that no fluid is delivered tothe applying roll 26. Operator-controlled means are provided including atrcadle-operated rod 102 adapted to move a level' 104 which bearsagainst one of a pair of hell crank levers 106 upon a shaft 107 andengaging stops 108 upon the extended outer ends of the rods 62 and 64.This arrangement allows the operator to bring the train of rolls into(fc-operative relation so that the fluid will be carried over from thereceptacle 30 to the applying roll 26 when the operator is ready topresent Work to the machine and to interrupt this delivery of cementWhen the presentation of work is to he interrupted.

Provision is made for driving the various rolls in the train from themain shaft 18, and the arrangement is such that the driving connectionsare not impaired by the various ad `iustments and movements oftranslation already described. The supplying l'oll, 36, the shaft 38 ofwhich is journaled in a part of the frame 10, is driven from the shaft18 by .means of bevel gears 110. In the sliding frame 60 a countershaft112 (Fig. 2) is provided, and this countershaft is driven from n themain shaft 18 by means of coacting spur 'gears 114 and 116, it being,noted that the spur gear 116 has a wider face than Vthe gear 114 so thatit will always remain in mesh with the gear 114 as the sliding frame 60is moved. Bevel gears 118, 120, oney upon the count-ershaft 112 and theother upon thc stud shaft 34, drive the transfer roll 32.

In order that the relative approach of the applying roll 26 and thetransfer roll 32 Imay be adj ustably controlled, the shaft 28 of saidapplying roll and other driving connections to be described are mountedin an adjustable bracket 122 having an extension 124 which is sleeved ina bearing 126 provided upon said sliding frame 60. A stub shaft 128,journaled in the extension 124 (Fig. 2), has a pin and slot connection130 with the end of the countershaft 112 and bevel gears 132 and 134 arepinned to the respective shafts 128 and 28 which provide a drivingconnection therebetween. A bolt 136 having a headed end 138 rotatablysecured in the bearing 126 is threaded in the adjustable bracket 122 andmay be rotated by means of a knurled head 140 and clamped in adjustedposition by means of a clamp bolt 142 in the bearing bracket 122.Another clamp bolt 144 is arranged to hold the bearing 126 in itsadjusted position. This arrangement provides for the adjustment of thedistance between the adjacent faces of the applying roll 26 and thctransfer roll 32, thereby to determine the amount of fluid carried overfrom one to the other.

A cover 150 secured to the bracket 7 4 by a bolt 151 and to the frame ofthe machine by a bolt 152 is arranged to conceal the operating parts andis provided, as shown in Fig.

- 4. with outwardly extending lips 153 having depending doWel pins 154tapered at their lower ends. The receptacle 30 is provided withapertured lips 156 arranged to be brought up into engagement with thelower ends of these don-'el pins in order to position the receptacleupon the machine, and this position may be maintained by means of alocking bolt 158 (Fig. 1) slidable in the main frame 10 and adapted tobe operated by means of a gear-and-rack connection to a hand wheel 160.This arrangement facilitates the removal and replacement of thereceptacle.

when it is desired to clean the same and insures the proper positioningof the receptacle Without excessive care y@n.the part of the operator. Asupply of cement or other fluid may be contained Within a tank 162, thearrangement being that of a barometric supply in which the level 164 ofthe fluid in thev receptacle 30 is determined by the position oftheoutlet opening of the tank 162, and this tion within the receptaclewithout spilling some of the contents thereof, especially when the tankis of any considerable size or Weight, will be readily appreciated.Accordingly, means have ybeen provided allowing the tank eto be placedin inverted position directly over the receptacle before the fluid isallowed to escape therefrom. To this end a butterfly valve 168 having aprojecting arm 170 is secured upon a sleeve 172 adapted to be insertedin the neck 174 of the tank 162 before the inversion of the latter, itbeing understood that the butterlly valve is then in closed position.The position of the sleeve 172 with respect to the neck 174 of the tankis determined by a collar 176 fixed upon said sleeve. The receptacle 30is then provided with a slot 178 (Fig. 5) to allow the admission of thearm 170 of the buttery valve, and as the tank is inverted and loweredinto position upon the receptacle, the arm 170 may be brought intoengagement with a side of the slot 178 and the tank given a partialrot-ation to open the butterfly valve. and then dropped immediately intoposition. y

It will be understood that the invention is not limited to anarrangement for applying cement to Economy insolcs since it may, withonly slight modifications, be equally Well used for ehannel-cementing orfor sole-inking. Fory either of these uses the work-supporting roll 42and associated parts will be dispensed with, and when the machine is tobe used for channel-cementing, a brush similar to that illustrated inthe earlierapplication referred to above will be substituted for thesolid applying roll 26. When the machine is to be user for sole-inking,either a solid roll or a brush may be used as .determined by thecharacter of the work and the nature of the ink to be applied.

The novel features of the herein-disclosed means for facilitating thepositioning of an inverted supply tank upon the machine are not claimedherein since they are claimed in divisional application Serial No.344,060 filed March 2, 1929.
